chocolate

I am going to try this Mass Gainer that I ordered from redcon1. It is called MRE and they say it is real food The pack says its 525 calories and 80g of carbs what do you think about this product it's oatmeal chocolate chip flavor and it tastes pretty good so far but I feel tired after drinking it

does anyone know of a protein powder I can add to my coffee that will taste good. So far the ones I've tried have made my coffee taste weird obviously adding chocolate flavored way is going to make the coffee taste funky. I need to fit in a scoop into my coffee to get my protein requirements
